CPU fan controller circuit
Catagory : Sensor circuits, Temperature control circuits
This circuit will turn on/off 12V DC fan or CPU fan when temperature above preset temperature.You can set turn on temperature by adjust VR1. This circuit use an NTC (Negative temperature coefficient) as a temperature sensor.The NTC is a thermistor that the zero-power resistance decreased when increase the temperature.

Celsius-to-digital thermometer works with remote sensor
Catagory : Sensor circuits, Temperature control circuits
This circuit use a single-supply system to precisely measure the temperature at a remote location with less than 1°C error over a 0 to 100°C range . The circuit includes a low-cost AD590 temperature sensor, an AD8541 rail-to-rail amplifier, four resistors, a trimming potentiometer and an ADC.

Dual Fan controller with AVR
Catagory : AVR microcontroller, Microcontroller, Motor control circuits, Temperature control circuits, Temperature related circuits
The project helps you control two fan’s to cool whatever you need by adjust the trimpot. It works by cooling with the first fan when the sensor detects a user adjustable temperature, and it turns the second fan on, when the temperature exceeds 5 degrees over the user adjusted temperature.Each fan turns off when the temperature drops 5 degrees below its turn-on temperature. For example, if the trimpot is set to 80 degrees, the fan turns on at 80 degrees and turns off at 75 degrees.The circuit controlled by ATtiny45.
